Material Notes:
Luran S Q440 is a low gloss extrusion ASA grade with excellent weatherability. Luran S Q440 is especially suited for the building and construction market as a low gloss weatherable cap layer. It is provided with a base loading of TiO2 to help in the coloring of the product with a color concentrate. How dark the final application is determines the level of TiO2 in a grade. The data representable is based on 0.125" thick extruded sheets in the cross flow direction.
